Claims

[Scope of utility model registration request]

In a hose joint structure that is applied to the connection of relatively low-pressure piping systems, an outer cylinder and an inner cylinder made of resin are connected by fitting with an O-ring interposed between the outer cylinder and the inner cylinder. A protrusion provided on either one engages with a corresponding notch provided on the other to prevent rotation in the circumferential direction, and is provided on the inner circumferential surface of the outer cylinder and the outer circumferential surface of the inner cylinder. A hose joint structure characterized by engaging stepped portions to prevent the hose from coming off in the axial direction.
